Hi all, I've got this Cory who's got fungus on his mouth and his fins, his barbels are like almost all gone, and his fins have some damage too. This happened mostly while I was on vacation, and when I got back I moved him to a hospital tank. I put in some Maracyn medication(not too much because I was afraid it would harm them), but it hasn't seemed to work. Are there any other meds or ways I can cure him?
Thanks!!!

It's a bit late, but never dose medications like Maracyn at low doses - always dose full dose.

You need to get that nitrite down to 0 for the fish to heal. I would start doing frequent waterchanges (making sure temperature is roughly matched so there isn't too much shock) - maybe 25% a day. Add a tiny pinch of salt to the new water before you put it in.

Sue will probably have something to add to this. _________________Fishing in the Rivers of Light
